Abstract

A modular family of electrical switching relays that utilize interchangeable mechanical override knobs or blank fillers, combined with enclosures capable of containing two or more independently operable relays; where each independent operating relay can selectively be constructed to either have a mechanical override knob or to have a blank filler thus resulting in a broad number of product permutations from a minimum number of unique components that are required to build those permutations. An electromechanical relay with rotary manual on and off override control where the manual on and off control consists of three distinct positions for (1) forcing/maintaining the relay on, (2) forcing/maintaining the relay off, and (3) allowing the relay to automatically turn on and off or to be remotely turned on and off with an electrical signal. An electromechanical push/pull relay with manual on and off override control where the axis of rotation of the manual override control is perpendicular to the axis of relay push/pull direction.
